I have submitted the following to the EX700 thread but thought as it concerns all panny panels I would post this on its own and see what your thoughts are with regards to Panasonic and Martin Dawes claims that my panel issue is normal and not sufficient for a refund/replacement and should I just give up. I understand banding is a misused word, its actually non uniformity on panning and dirty screen along the top and bottom, the vertical bars are worse in the middle of the screen and more noticeable on lighter backgrounds but can still be seen on the likes of football.
Below is what i posted, thanks:

I am still having issues with John Lewis and my TV. They say as Panasonic and the engineers state its ok then they cant override that decision so they wont refund/replace.
I have asked for copies of the reports from both engineers.
The TV still suffers from pixelation/macroblocking from all sources and the only way I can sort of fix this is to adjust the settings so that its a lot brighter than it should be, so now most of the time its like its washed out and the black is too bright. I have to depending on what I watch go from custom (my settings for pixelation) to true cinema (on line recommend settings) or tweak the settings for that particular program. Its ok but not brilliant. I shouldnt have to keep tweaking!
My main concern now is the DSE/Banding non uniformity, it really annoys me and seems to be getting worse as that is what I look out for now (once seen cant be unseen) so I am not enjoying the TV as I should be, so basically its not fit for purpose.
I sent Panasonic who by the way are ignoring me, videos and photos but they said they are not good enough so will need an engineer to visit however when NWAR sent the exact same videos/photos all of a sudden they were good enough for them to say within spec. even though the videos of the DSE/banding are not clear at all and you have to watch it in the flesh to see how bad the vertical bands are. Both engineers could see what I was on about to a point Martin Dawes changed the panel (they pointed out the DSE) but the panel they fitted was damaged so they refitted my old one and said its within spec.
When NWAR returned my TV he asked if John Lewis was going to replace it and was shocked when I said no.
The last time Panasonic contacted me they said the issues are down to the source, I asked them to confirm that they are saying DSE/banding etc is a source issue but they ignored me. "In regards to your query, I would like to inform you that the service engineer has discussed the issue you encountered on your TV with our technical team, which advised the content has this aspect due to the graduation in the steps of the video signal.This is not a fault".
When I received a copy of the report from Martin Dawes it said the following:
"There is several reasons why the customer is having issues. This will be down to the compression of the program the client is watching and from what source. Regards to the banding this is out of our hands it's down to the way panels are made and distributed via the manufacturer. Most of the brands have some kind of banding issues. You could change 10 panels and get 2 OK panels."
Martin Dawes told John Lewis the TV is within spec on all issues but in the report they state that their are issues with panels with all manufacturers (panel lottery!) Now does that report state the panel has a known manufactures fault as to me it does. When I bought the TV no where did it state in the tech specs that I may have DSE/banding/non uniformity, no where did it state in the manufactures jargon and reviews that I would have these issues and when I spoke to the TV sales guy in john lewis he didnt tell me I would have this issue with DSE/banding/non uniformity in fact he said it would be a good enough TV to replace my aging plasma. The TV in store I looked at didnt have these issues either and only the other day I went in store and non of the LED TVs on display had DSE/banding/non uniformity that I could see. The Panasonic equivalent model to this was perfect. So what next?

p.s. this is the NWAR report "
REPORTED FAULT BANDING O SCREEN AND POSSIBLE MACROBLOCKING ON SCREEN
ENGINEERS REPORT THE TELEVISION WAS TESTED IN THE WORKSHOP ON VARIOUS SOURCES AND FOUND TO BE WORKING NORMALLY,BUT BECAUSE OF THE CUSTOMERS CONCERNS ABOUT BANDING ON SCREEN AND MACRO BLOCKING THE CUSTOMERS EMAIL WITH THE PHOTOS AND VIDEO CLIPS OF THE ISSUE REPORTED WERE SENT TO PANASONIC TECHNICAL ALONG WITH PHOTOS AND SPECIFIC VIDEO CLIPS THAT THEY REQUESTED FROM US FOR THEM TO ANALYSIS AND THEY SAID THERE WAS NO ISSUE WITH THE TELEVISION."

If these issues do not show up straightaway, then you are at the mercy of these f,,,,,.s and they do not want to know, they are all the same, except LG when they first brought out OLEDS.
